Health professionals, especially diabetes nursing specialists, have been training diabetes patients on the understanding and self-caring of diabetes. However, with the emerging concept and preliminary evidence of success in the role of "peer advisors" in diabetes to lead self care courses for other fellow patients, a train-the-trainer program to develop "expert patients" is essential. On top of factual knowledge on diabetes as a disease, context of this program needs to cover include communication and empowerment skill, basic knowledge on psychology, stress management, social support, empowerment, healthy lifestyle including diet and physical activity.
